Apple has officially seeded the first beta of iOS 9.3.3 to developers for testing purposes, one week after iOS 9.3.2 was released to the public, which brought about a Bluetooth fix for iPhone SE models and other improvements.
We don’t yet know what changes iOS 9.3.3 will bring to iOS 9, but as a minor 9.x.x update, it’s unlikely to introduce any major tweaks. There is no iOS 9.3.3 update available for the 9.7-inch iPad Pro, suggesting the new beta does not fix an issue that bricked some 9.7-inch iPad Pro devices. Apple has also pulled the iOS 9.3.2 update for the 9.7-inch iPad Pro and has not re-released it.
Registered iOS developers can grab the new build, which is labeled version 13G12, from the Apple Developer Center, or via an over-the-air update on a compatible device with the latest software.
We expect iOS 9.3.3 to be a fairly minor update, and to be made available to the public in short order. Remember that WWDC is now just a few weeks away, and Apple is expected to use its keynote for the event to unveil the next version of iOS and its other platforms.
